How much is a tornado worth?

Excuse me, could you please elaborate on the context behind your inquiry? When you ask "How much is a tornado worth?", it seems to imply a monetary valuation, which is somewhat unconventional given that tornadoes are natural disasters. Are you referring to the potential economic damage caused by a tornado? Or perhaps you're inquiring about the insurance coverage for such an event? Clarifying your question would help me provide a more accurate and relevant answer.
